VEHICLE-WHEEL.

To all whom it'ma'y concern:

Be it known that I, How C. GIBSON, a

subject of the King of Great Britain, and a resident of New York, in thecounty of New York and State of New York, have-in.-

vented certain new and useful Improve lates more particularly to that.class of wheels-in'which a metallic rimv carrying a pneumatic tireisdismountably secured to the spokes of the wheel;

One of the objects of my invention is to i. provide a constructionwhereby a tire-hold- "ing rim may be demountably secured to a wheel andeffectually held. thereto by friction in such a manner that the clampingdevices will not become wedged or jammed An object of my invention inone .of its forms is to dispense with the telly ordinarily used invehicle wheels of this class and to provide a wheel with a dismountablerim which will nothave to be ang'ularl'y located.

when placing it upon the wheel and which will be capable ofself-alinement. I

Another object of my invention is to pro vide eachspoke of the wheelwith an indi-- vvidua l clamp which will rigidlyholdthe rim in place byfriction and thus dispense with the provision of special devices securedto the rim by which it is attached to the wheel.

A further object is to -providean tip a. ratus wherein the rim 'canfbevery rea ilyand quickly removed from and replaced upon the'wheel and atthe same time one which will be very'simple in construction and of lowcost to manufacture.

A still further object is' to provide a wheel f with a 'di'smountablerim which canbe taken from the wheel without entirely removing theclamping means therefrom.

a To these ends my invention consists broadlyin providing a vehiclewheel with fixed means adapted to' engage the rim on .one side andmovable clamping levers fulcrumed or seated onprojections on the wheel-'for engaging the rim on theother side.

yetwill securely gripand hold Patented Man-14, 1911.

My invention alsoconsists in the improved, individual clamps secured tothe ends of the spokes for frictionally engaging the wheel rim ashereinafter specified in the claims.

My invention consists further in so con- :structing the device that theWeight and shock 'to which the rim is subjected. will be transmitted'tothe spokes and-"Jhub of the wheel instead of actln direct on the nutsand bolts which hold t e rimyin place as is the case in the devices ofthis class at present onthe market.

My invention consists furtherin the details of construction andcombinations of parts hereinafter more particularly described andthenspecified in the claims.

In the accompanying drawings,' Fi re 1 illustrates inside elevation awhee constructed according to my invention." Fig. 2

through the tire, rim and preferred form of clamping device, the spokebeing shown in side elevation. Fig. 3 illustrates a vertical centralsection through a modified form. Big. t is a similar view of a furthermodification. Fig. 5 is a plan View of the 'modi- 'fied clamping device.shown in Fig. 4. 1 indicates the hubof a' wheel; provided with spokes 2extending radially therefrom as is'usual infth'e art. a 1

According to my invention in its preferred form the usual permanentlyattached fel'ly is not employed, but the spokes 2 are eachprovided attheirend with a clamping device which engages the rim 3 by clamping on Ithe periphery o the rim. as will be presently described. The rim 3 ishere shown as being the usual standard clencher type rim,

provided-with the usual tire 4, but obviously.

might be any other form of rim suitable to vbe-engaged and held byfriction ofthe clamping devices.-

In the preferred form of carrying out my in'ventionft-he e'ndsof thespokes 2 are of smaller diameter than the mainportion and 3 I i areprovided. with-a shoulder 2'. Over the small endis snugly fitted ahollow metal "casting or forging forming a socket 5, the lower end ofWhlCh rests upon the shoulder 2'.

Theupper partof the socket 5 is provided with an outwardly and upwardlyextending arm 6, preferably integral theree -with,which engages one sideof the rim 3 on its-curved surface, that is, where the rim by. the armscurves outwardly to form the usual clencher for the tire 4, or it mightenga e'a similar or angularly disposed surface 0 other suitable forms ofrim.

Referring more particularly to Fig. 2, a movable clamping memberconsistingpreferably of an arm or lever -7 engages the other side of therim 3 on its curved surface. The movable lever 7 is fulcrumed on a lugor shoulder '5 projecting from the side of the socket 5 and providedwith a centrally located slot 8. A bolt9 having its head located withinthe hollow casting forming the socket 5 passes through a suitableopening in the side of the casting and through the slot 8 after which itis provided with a suitable nut 10 by which the movable clamp is drawnup to the socket and tightened upon the rim. The lower end of the arm 7having a solid bearing on the projection or shoulder 5. a great pressureis exerted upon the rim to grip and clamp it between the arms 6 and 7when the arm 7 is forced up.

by the nut 10. Preferably a coiled spring -11 compressed between thesocket 5 and the arm 7 forces the said arm away from the rim when theclamping nut 10 is loosened.

The rim being in its preferred form entirelysmooth on its innerperiphery can be placed .on the wheel without any regard to its angularposition and will be brought into proper alinement by the tightening upof the clamps, the rim beingextendedto its furthermost position at thesametime v and rigidly held in place by the friction between it and thearms 6 and .7. As will be obvious all thatis necessary to do in order toremove the rim from the wheel is to loosen the nuts lO and the arms 7will be forced away from the rim by the springs 11,

the'arm turning about its seat on the lug 5 as a pivot after which therim isreadily removed and a new one substituted. Also as will be obviousall the weight and shock on the rim whether transmitted to the fixed .ormovable clamping arm will be brought, to bear direct upon the spokes andhubof, 'the wheel, the movable arm transmitting the shock totheprojection on which it is seated o'r fulcrumed. v

In the modification illustrated in Fig. 3 the movable clamp 7 ishinged-or pivoted 'to ,the casting forming socket 5, thevs ring 11 beingpreferably wound around-t e pivot:

and held under tension between the arm 7 and the socket 5 as shown.

Referring to the modification shown in Figs. 4 and 5, the movableclamping member consists of a roller 12 riding upon an inclined surface13 formed on the casting 5 and drawn up into engagement with theperiphery of the rim to clamp the same by the nut 10 and washer 14. Aspring 15 secured to the ends of the roller 12 serves to positively drawthe roller away from the rim I segue when released and also prevents theroller falling from the device when loosened.

Whlle I have shown and prefer to use a spring to positively force themovable clamping member from the rim, it will be obvious that I do notlimit myself to the use of this spring as my invention is equallypracticable without utilizing any 'sprln lVhile' I have here shown anddescri' ed a rim of the standard .clencher type,'it is obvious that myinvention is not limited to the same as other suitable forms of rimmight be employed presenting a similar surface to be frictionallyengaged bythe arms of the clamping devices without departing from thespirit of my invention. Also it would be within the scope of myinvention to make both arms of the individual clamping 1 devicesmovable.

- It will also be noted that by practicing for the tire of the usualconstruction as for pneumatic tires as previously constructed it isnecessary to use specially constructed lugs for the purpose, mainly onaccount of the felly of the wheel being retained.

construction with the old forms of detachable rim the telly would haveto be cut away to allow for the lug which practice is very objectionableas can readily be seen. i What I claim as my inventionis:
